(hie ot the great problems ot the householder is to ovoid doum e to or even destruction ol? garments, :turs, "s, and other things l inoth lerrte end. on. or insect lite, and it iiversel custom to i'cold storage during when they are not in use, Other ihst not to he used. at the time, it not phced in cold storage, must he eon stsntly Watched, us iiuis't rugs end other things that torn]. od :ior insects, in order to prevent then-1 :rom being damaged; this piece expensive i'urs the i neccsor constantly Watching ones goods cons inconvenience and unnoyziuce, even it one happens to he methodical enough not to forget to keep watch.

It hes long been lo'io'wn that insect life, even in the stage, nioy he destroyed by maintaining on atmosphere con'iposed oi the vapors of any one ot several so ulled "fulfil" gents, and entire rooms have been treated With. these tun'iipnnts for the purpose of do stroying insect life in end on the rugs, turniture and other things it'orining the furnishings of such rooms, and. especially built roon'is orchemhers have been provided for treating; goods of "various kinds on a. large scale.

lit a householder attempts to destroy the insects hy :tuini i g the house, the latter must either he ehsndoued as it huhitstion for ineny oours, or the work must he done one room ut e t' no. In either event, the process interferes "with the normal use oi? the house end, since most oi? the ellecti've tun'ii reting nioteriels huV-e disagreeable odors, it is not pleasant for the householder to go through either of these processes oi? protecting his goods, and it is therefore very seldom done.

The most satisfactory my of treating or processing; things to clezinse them oi? insect life would he to place them in airtight cuphourds or portable vui'ilts and there surround them with u lite-dostroyin r utn'iosphere.

lVhile in intention n'iuy telce rarious other forms end he used for other pin-poses then ouphourds, ll: here illustrated only a single term as applied to o cuphonrd end, for the sake oft brevity, shall confine the detoiled description to this particular form and use. i i

The structln'e shown in the drawing is shown as being squorc in trziusverse section and 0t on desired he' it; the trout roll. having; a. door openii to which o. door may he pplied. The inoteriol out oi? which the device is made is preferably plyinetol, which takes the i'orni of panels composed ll U - to the third section, the

; the lines of the grooves, each will comprise three sections two of which are arranged parallel with each other and at right angles metal sheathing being continuous past the corners between the sections. One of these panels is shown in Fig, 7, there being two V-shaped grooves A and B that divide the panel into a central section land two side sections 2 and 3. \Vhen the sections 2 and 3 are, folded downwardly, as viewed in Fig. l, they take up positions at right angles to the central section so as. to form the rear wall and parts 2 and 3 of two adjacent side walls of the cupboard, as shown in Fig. l. The other panel comprises a central section 4: and two side sections 5 and 6; the section a forming the front wall of the cupboard and the sections 5 and 6. cooperating respectively with the sections 2 and 3v to complete the two side walls. The front wall. has a door open ing 7. In order to permit the meeting edges ofthe. two panels to. be securely fastened together so to make an, airtight joint. I cut, away a, portionv of each panel on the inner siidealong the vertical edges, to produce portions 8 of reduced thickness. hen the meeting edges of the panel are brought together, each meeting pair of thinv marginal: portions 8, will form the bottom ofa comparatively wide, grooye extending throughout the; length of the panels. Into each of these grooves there is pressed, tights 1y a strip, of wood 9 held in place by means of nails arranged closely. together in two rows 10 and 11 lying on opposite sides of the plane of' contact between, the corresponding edges of the panels. The ends of the panels, only one of which is shown, are reduced in thickness, preferabl'yfor a dis tance somewhat greater than the thickness of the material out of whicn the panels, including the top section, are made, by cutting away a marginal portion on the inner side so as to forma continuous shoulder 12 facing upwardly or downwardly, as the case may be. members, only one of which is shown, but which may be duplicates of each other, are provided with marginal portions reduced in thickness by cutting away the wood or wood pulp and producing a continuous shoulder around each of the same and facing toward the edges; the top or other end member being indicated at 13 and the shoulder on the inner side of the same at 14.

The top and bottom end- The end member is made of the proper size to fit into the end of the body member of the structure beyond the shoulder 12 in the latter. It will be seen that the shoulders 14:, together with the inner faces of the reduced marginal portions of the end member and side walls will form a continuous square or r ctangular passage extending around the inside of the structure if the outer surface of the end member is located flush with the plane of the extreme outer edge of the body member. In this rectangular passage I place a strip of compressible, more or less elastic material, through which air will not pass; the compressibility and the elasticity of the strip insuring an airtight contact between the same and the engaging faces of the sides and end of the structure if it i held in place under compression. The material I prefer to use for the strips is wood, they being made of the proper lengths to lit into the spaces provided for them and somewhat larger in transverse dimensions than the corresponding dimensions of such spaces. are preferably attached first to the end member. In doing this, I place the strips 15 in the form of a irame upon which the end member is set, as shown in Fig. 2, the reduced marginal portions of the end mom ber resting on the strips and the continuous shoulder let engaging with the inner sides or faces of the strips. Assuming that the line 3 represents the top of ahat table or the like,,pressure is exerted on the end n'nunbcr l3 and the strips in the directions oi the arrows in Fig. 3, the pressure being great enough to produce an actual compression of thestrips or of the wood or pulp board of the end member, or both. While this pressure is being maintained, the end member is nailed to the strips by means of nails 10; these nails extending in a continuous line across the end member near each edge there of, best shown in Fig. 1. After the pressure is removed, the strips may bulge outwardly more or less. as indicated in Figs. 5 and 8. In, this event, it the end to be applied to a completed body member, 1 chamfer the strips along the lower outer corners as indicated at 17 in Fig. 5, so as to permit thestrips to be started, into the space within the end of the body structure. Pressure is applied in the direction of the arrows in Fig. 5, not only a downward pressure on the end member, but also an inward pressure on the reduced marginal portions of the body, so that the strips will be compacted, as shown in. Fig. (i, in which condition they are united to the side walls of the bot y member by means of. nails 18 arranged close together in rows, as best shown in Fig. 1.

Instead of forcing the end member into the end of a completed body member, the

The stripsv lid till

the two side sect nesanse panels of whichthe body member is made can be folded around the twoeiid members, suitable apparatus being proridcd to exert the necessary pi at the desired points. Thus it will be seen that it" an end member is placed in the same relatiye position to one of the panels, as Sais related tollig. 7, the central section oi the panel may be engaged with, one er" ge of the end member, and as may be folded downweirdly and inwardly into. coi'ltact with two other edges oi? the end member. llhile the partsarein these positions, the nails may beapplied to fasten the sidewall sections oilthe structure to the, end niiel nber or scetion lt will thus be seen that I have provided cheap, light and simple box il ei structure in which the joints will beairt so that alter the same has been; closed by a suitable sealed door, itmay be used succ s fully to etlfect the extermination of all insect life that may be preesnt within the same.

l l' hile l hare illusl'ratelil and described with particularity only a single preferred l orm cl? my invention, I do not desire to be limited to the exact structural details thus illustrated and described; but int end to cover all forms and arrangements which some within the terms employed in the definitions of my invention constituting the appended claims.

l claim:

1. The method oli forming a. scaled joint between an end member and the side walls of a vault which consists in so shaping an end member and side walls that the end member will lit into the space between said walls and overlie a shoulder extending along the l tter adjacent to the mar inal portion of said end member and the end member will have a shoulder lacing outwardly on the inner side thereof and extending around the said. mem her at some distance from the edges thereof, compressing an elastic scrip into the angle helix ,n the shoulder and the inner n'iarginal suiul'acc on said'member in a direction paral lei to the plane of said member to a degree within the elastic limit of said strip, secursaid strip to said member while in a com pressed condition, assembhig said member and said walls and further compressing said strip into the angle between the shoulder and inal. portions on said walls to a do gree within the elastic limit of said strip, and securing said marginal portions of the walls to said strip while the latter remains under compression.
